Changelog

[0.6.1] - 2024-05-04

What's Changed

  • Use Blob instead of File for input in ParquetFile.fromFile.
  • Export wasm paths from package.json.

[0.6.0] - 2024-04-21

New! ✨

  • Class-based API + concurrent streams + column selections + File reader by @H-Plus-Time in #407. This added a new ParquetFile API for working with files at remote URLs without downloading them first.
  • Conditional exports in package.json. This should make it easier to use across Node and browser.
  • Improved documentation for how to use different entry points.

Breaking Changes:

  • arrow2 and parquet2-based implementation has been removed.
  • Layout of files has changed. Your import may need to change.
  • Imports are now parquet-wasm, parquet-wasm/esm, parquet-wasm/bundler, and parquet-wasm/node.
